Theres a lack of music. But the art is really good, the bosses are really creative, and the final boss is really climactic. I blasted boss music while playing, and it fixed it, but this game still needs sound. The controls are hard to pick up, using the arrow keys alongside Z X C are tedious sometimes, but its overall not a bad game. I'd say it's pretty good. It feels like you got better at coding as you worked on it, given how rapid the complexity of the boss's attacks get the more you progress through the game. Its overall a solid game, but still needs sound, and gamepad support would be very nice.
